摘要: This paper focuses on the integration and data transformation between GPS and totalstation. It emphasizes on the way to transfer the WGS84 Cartesian corrdinates to the local two-dimensional plane coordinates and the orthometric height GPS receiver, totalstation, radio, notebook computer and the corresponding software work together to form a new surveying system, the supertotalstation positioning system (SPS) and a new surveying model for terrestrial surveying. With the help of this system, the positions of detail points can be measured.
